TO be honest, I have let my tank go, well you know bad animal husbandry. Anyway, I now have that urge to get it going again and I want to replace the substrate. I have crushed coral, which is about 5 years old and very dirty looking. I was thinking of replacing it with the white sand I see around. Do not know which brand or type is best. Any suggestions? Tank is 90 gallon, fish only.
